The Thai Meteorological Department (TMD) forecast came as the moderate high-pressure system from China extends to the Northeast and the South China Sea, while hot weather continues in the northern regions of the country.
“People in upper Thailand should beware of severe conditions by keeping off outdoor places, big trees and unsecured billboards and keep healthy due to changeable weather,” the department said.
“Farmers should prevent for crops damage and animals danger.”
The TMD forecasted that the easterly wind will prevail over the Gulf and the South, bringing isolated thundershowers. The wind and waves in the Gulf and the Andaman Sea are expected to reach about one metre in height, and higher in thundershowers.
The department predicted that the easterly wave will move across the East, the Gulf, and the South into the Andaman Sea, bringing more rain, with isolated heavy to very heavy downpours and gusty winds from March 31 to April 3.
